Before such license is issued by the Director of Consumer Protection and Business Licensing, the applicant will be required to post a surety bond in an amount of $1,000, with a surety company licensed to do business in the State of Maryland. Said bond shall be approved as to form and sufficiency by the City Solicitor before such license is issued. The condition of such bond shall be:that said transient merchant will well and truly perform any and all contracts or sales orders made within the City; and more particularly, that if said merchant takes orders for merchandise to be delivered at a future date and accepts payment in part or in full therefor, he will deliver said merchandise in a satisfactory condition within a period of 4 months from the date of said contract, copy of which contract or sales order with full particulars is to be delivered to the purchaser at the time of sale. There shall be no forfeiture in respect to the 4-months limitation where there is proof that nondelivery was due to strikes or other extraordinary events beyond the control of said merchant. However, in such event the merchant upon demand shall promptly return in full the purchaser’s deposit; and, if he fails so to do, the surety will be required to make restitution under said bond. City Code, 1976/83, art. 15, §101(d) Ord. 71-1212
